Installation Instructions

I'd like to use raspi-live, either the newest version or the old one. The old one worked great and I'm having to rebuild my rpi so I'd like to use this again.

However, the old one appears to no longer work and the "Download the latest version of raspilive from the Releases page" doesn't give enough info. Tried it using wget with the release asset and running but it's a no-go.

I'd assuming Go must be installed first? If so what version?
And if it requires 'go install raspilive" what is required for that to work? Tried that a few ways and it didn't work either.

Since I no nothing about Go, detailed steps to get this working are appreciated. Thanks.

Start from the existing “Download the latest version of raspilive from the Releases page” installation guidance and the release assets. Check the expected Go prerequisite, version, and whether `go install raspilive` is supported, then document the required steps for Raspberry Pi users. Done means a newcomer can install either the latest or older version without guessing.
